The invention relates to a copying method which comprises the following steps: receiving a copying instruction for a processing object; acquiring the processing object by responding to the copying instruction; sending the processing object to a server. According to the copying method, data copied by a first terminal are uploaded to the server, and when a second terminal receives a paste instruction, the copied data are downloaded from the server and pasted, so that remote data copying and pasting are realized; therefore, the data processing efficiency is effectively improved, and data loss is effectively avoided.
